Techniques for Unifying Etl Filter Operators

2. The method of claim 1, wherein the ETL plan further comprises a plurality of data pipelines following the split operator, the plurality of data pipelines having at least one filter operator of the plurality of filter operators on each data pipeline.

3. The method of claim 1, wherein the unified filter operator comprises a first condition of a first filter operator of the plurality of filter operators joined by unifier logic with a second condition of a second filter operator of the plurality of filter operators, wherein the unifier logic comprises an OR operator.

4. The method of claim 1, wherein: the unified filter operator implements a portion of a filter operation of a filter operator of the plurality of filter operators; and the ETL plan comprises a residual filter operator acting on data output by the split operator in the ETL plan, the residual filter operator and the unified filter operator together effecting the filter operation.

5. The method of claim 1, wherein the ETL plan further comprises a transform operator between the split operator and a filter operator of the plurality of filter operators, the method further comprising: excluding the filter operator from the unified filter operator.

6. The method of claim 1, further comprising: presenting, by the computer system, the updated ETL plan via a user interface.

8. The computer system of claim 7, wherein the ETL plan further comprises a plurality of data pipelines following the split operator, the plurality of data pipelines having at least one filter operator of the plurality of filter operators on each data pipeline.

9. The computer system of claim 7, wherein the unified filter operator comprises a first condition of a first filter operator of the plurality of filter operators joined by unifier logic with a second condition of a second filter operator of the plurality of filter operators, wherein the unifier logic comprises an OR operator.

10. The computer system of claim 7, wherein the unified filter operator implements a portion of a filter operation of a filter operator of the plurality of filter operators; and the ETL plan comprises a residual filter operator acting on data output by the split operator in the ETL plan, the residual filter operator and the unified filter operator together effecting the filter operation.

11. The computer system of claim 7, wherein the ETL plan further comprises a transform operator between the split operator and a filter operator of the plurality of filter operators, and wherein the computer-executable instructions, when executed, further cause the one or more processors of the computer system to perform steps comprising: excluding the filter operator from the unified filter operator.

12. The computer system of claim 7, wherein the computer-executable instructions, when executed, further cause the one or more processors of the computer system to perform steps comprising: presenting, by the computer system, the updated ETL plan via a user interface.

14. The computer-readable storage medium of claim 13, wherein the ETL plan further comprises a plurality of data pipelines following the split operator, the plurality of data pipelines having at least one filter operator of the plurality of filter operators on each data pipeline.

15. The computer-readable storage medium of claim 13, wherein the unified filter operator comprises a first condition of a first filter operator of the plurality of filter operators joined by unifier logic with a second condition of a second filter operator of the plurality of filter operators, wherein the unifier logic comprises an OR operator.

16. The computer-readable storage medium of claim 13, wherein the unified filter operator implements a portion of a filter operation of a filter operator of the plurality of filter operators; and the ETL plan comprises a residual filter operator acting on data output by the split operator in the ETL plan, the residual filter operator and the unified filter operator together effecting the filter operation.

17. The computer-readable storage medium of claim 13, wherein the ETL plan further comprises a transform operator between the split operator and a filter operator of the plurality of filter operators, and wherein the computer-executable instructions, when executed, further cause the one or more processors of the computer system to perform steps comprising: excluding the filter operator from the unified filter operator.
